5.0 cover with a drain plug

looks good went on easy , I which it was cheaper but this was the cheapest i could find it so over all happy with it, I was only looking for a cover with a drain plug : /

5.0 Awesome quality

After having larger tires installed I realized that all the extra weight from the larger tires and wheels would definitely cause my differential to work harder. Had 4wheelparts install this differential cover for added oil capacity which with double the amount of diff oil means it’ll help keep rear diff much cooler and the added milled grooves add additional cooling and look absolutely kick butt! This cover is made in the USA and had absolutely outstanding craftsmanship! I’m getting one for the front next week as soon as I have time to have 4wheelparts install it. Absolutely awesome quality!
